SPINDLE FOR TEXTILE MACI-IiNERY Filed Aug. 2, 1950 nv VEA/ TC/P ATTOIPI/E'y Patented Dec. 11, 1951 SPINDLE FOR TEXTILE MACHINERY I Eric Findlow,Macclesfield, England, assignor to Ernest Scragg & England Sons Limited, Maeclesfield,

Application August 2, 1950, Serial No. 177,144 In Great Britain August 11, 1949 3 Claims. (01. 57-434) This invention has reference to spindles for a textile machinery and has for its object to provide means whereby the lubrication of the spindles is more eiTectively carried out and controlled than at present, and whereby oil splashing and waste of oil is avoided.

According to this invention, the lower end of a spindle is provided with a surrounding and enclosing cup, preferably transparent in whole or in part, such cup being secured detachably on the spindle or on its support and enclosing the lower part of the spindle and being covered or closed by a detachable cover, whereby the whole of the spindle bolster and bearing is enclosed in an oil-tight or substantially oil-tight cup.

According to one embodiment of the invention as applied to a spindle mounted on a swinging arm the support for the spindle bolster at the end of the swinging arm is externally screw threaded, and a cup with internally-threaded mouth is provided, preferably made of transparent material, and having a fiat bottom and widened at the top to surround the said support for the spindle bolster. The bottom part of this widened part of the cup is the internally-screwthreaded portion so that, if the cup be-pushed up over the part of the spindle bolster below the support, it can be screwed on to the screwed part of the spindle support already referred to, the wider part of the cup extending some distance above, and preferably above the bottom end of the spindle Wharf.

A detachable cover for the wider top end of the cup is provided, in the form of a circular plate, the plate having a slot surrounding the spindle swing arm, and the cover is held down on the cup by screws passing into the wall of the wide part of the cup which may be flanged or thickened for this purpose.

As already stated the cup is preferably flat at the bottom so that, when detached it can stand up and avoid spilling any oil there may be in it, and it may be provided or formed with a hexagonal or other angular shape, to afford a grip for screwing and unscrewing.

One example of the invention is illustrated in the accompanying drawing, the single figure of the drawing being a part-sectional elevation.

The example illustrated is of a spindle carried by a swing arm mounted on a vertical spindle.

The spindle I carries the boss 2 of the swing arm 3, the vertical part 3 of which arm carries the support 4 for the spindle bolster 5. The outer edge of the support 4 is screw-threaded and receives the internally-threaded part a cup 1.

The cup is of a transparent material and has a main portion of smaller diameter, and an upper portion of larger diameter, it being the upper portion which screws onto the support 4. The bottom of the cup is flat, and has a hexagonal protuberance l to receive a spanner for tightening and releasing purposes.

Secured to the otherwise open top of the cup 'l, by means of screws 8 is a cover plate 8, slotted at 9 to fit around the part 3* of the arm 3, and this plate has its central orifice 80,2.1'18Jlg6d as to fit over the flange 9*- of the spindle wharf 9. There is also an oil hole I0 in the cover plate in register with a passage II through the support 4, the wall of the cup I being cut away below such passage to allow free flow of oil into the cup. There is a filter disc I2 located in the passage II. The lower end of the spindle bolster '5 is screw-threaded exteriorly to receive the nuts I3 by which the compression spring I4 is adjusted, this spring re-acting between the uppermost nut I3 and the under face of the support 4.

Also, the bolster is drilled and tapped axially at its lower end, to receive a screw plug I5 on which the lower end of the spindle rests. There are radial holes It in the bolster to allow oil from the cup .7 to have access to the spindle and its bearings.

When the cup I is in place with the cover 8 on, the spindle bolster can be oiled and the oil will be safely retained in the cup, the contents of which are seen. There will be no oil splashing and no waste of oil and there will be no fiuiT or dirt adhering to oily parts; the economy in oil and cleanliness are thus very marked.

The bottom part of the spindle bolster is hollow and becomes filled with oil up to the level of the oil in the cup.

The spindle is held down by a trigger I1 secured on the spindle bolster 5, a hole I0 being provided in the cover plate 3 to allow it to pass. The trigger is resilient or resiliently mounted so that it can easily be pulled back to allow the spindle to be removed and will automatically give, and return to its holding position when the spindle is mounted.

I claim:

1. A spindle mounting for textile machinery comprising a support, a bolster carried by and extending below the support, a cup-shaped member detachably held on the support and enclosing that part of the bolster below the support,

3 a mouth carried by said cup-shaped member in encircling relation to and extending above said support, and a detachable cover plate on said mouth of the cup-shaped member, above the said support.

2. A spindle mounting for textile machinery according to claim 1, wherein the bolster is hollow and has radial holes to allow access of oil from the cup to its interior, and has an inserted screw plug at its lower end on which the spindle rests.

3. In combination a spinning spindle with a spindle wharf, a hollow bolster receiving the lower end of the spindle below the wharf, a removable plug in the bottom of the bolster to support the spindle, a support for the bolster having] an externally-threaded circular part, and a transparent cup screwing on to said threaded part, said cup being formed with a mouth extending above the support and having a detachable cover plate, said cup enclosing the bolster and support, with means for admitting oil to the cup, and from hence to the interior of the hollow bolster.

ERIC FINDLOW.
